SAFETY CONSIDERATIONS
Due to system pressure, moving parts and electrical
components, installation and servicing of air conditioning
equipment can be hazardous. Only qualified, trained, service
personnel should install, repair, maintain or service this
equipment.
Observe al l precautions in the li terature, on labels an d tags
accompanying the equipment whenever working on air
conditioning equipment. Be sure to follow all other safety
precautions that apply.
Wear safety glasses and work gloves, and follow all safety
codes. Use a quenching cloth and have a fire extinguisher
avail able for all braz in g op er ations.
GENERAL
YORK Model BCH units are single package heat pumps
designed for outdoo r ins tall at io n on a ro ofto p or a sl ab. These
units can be eq uipped with f actory in stalle d elec tric heat ers f o r
cooling/heating applications .
The units are completely assembled on rigid, permanently
attached base rails. All pipi ng, refrigeran t charge, a nd electrical
wiring is factory installed and tested. The units require electric
power, duct connections and installation of fixed outdoor air
intake damper (units without economizer or motorized damper
option only) at the point of installation.
The supplemental electric heaters have nickel-chrome
elements and utilize single point power connection.
INSPECTION
As soon as a unit is received, it should be inspected for possible
damage during transit. If damage is evident, the extent of the
damage should be note d on the carrier’ s fre ight bil l. A se parate
request for inspection by the carrier’s agent should be made in
writing. Refer to Form 50.15-NM for additional information.

WARNI NG: Do not permit overhanging structures or shrubs to
obstruct outdoor air di sc ha rge out le t.
DUCTWORK
Ductwork should be designed and sized according to the
methods in Manual Q of the Air Conditioning Contractors of
America (ACCA).
A closed return duct system shall be used. This shall not
preclude u se of ec onomizers or outd oor fres h air inta ke. The
supply and r eturn air duct connections at t he unit should be
made with flexible joints to minimize transmission of noise.
The supply and return air duct systems should be designed for
the CFM and static requirements of the job. They should
be sized to matc h the dime nsions of the duct connect ions on
the unit.
CAUTION: When fastening ductwork to side duct flanges on
the unit, in sert screws throug h duct flanges only.
DO NOT insert screws through casing.

FIXED OUTDOOR AIR INTAKE DAMPER
This damper is shipped inside the return air compartment. It is
completely assembled and ready for installation. A damper
baffle inside the hood is adjustable to provide variable
amounts of outdoor air intake on units that are not provided
with an economizer or a motorized damper option.
Gasketing and mounting screws are provided in a parts bag
attached to the hood assembly. Apply gasketing to the three
flange surfaces on the hood prior to installing the hood. Extend
gasketing 1/4" beyond the top and bottom of the two side
flanges to insure adequate sealing.
FIG. 4 -
RECOMMENDED DRAIN PIPING
Adjusting the damper to the desired air flow may be done before
mounting the hood into position or (after installation) by
removing the front hood panel or the screen on the bottom of
the hood. Damper baffle in po sition 1 will allow appr oximatel y
10% recirculated air f low , pos ition 2 appro ximatel y 15% and, to
allow approximately 25%, remove the damper baffle.

Secure with the screws provided.
On units with side return air ap plications, install the damper
assembly on th e return air duc twork as close to the unit as
possible. Cut an opening 16" high by 18" wide in the ductwork
to accommodate the damper. Using the holes in the hood
flanges as a template, drill 9/64" dia. (#26 drill) holes into the
ductwork and secu re with the screws provi de d.
CAUTION: If outdoor air intake will not be required on units

with bottom return air applications, the damper
assembly s hould still be moun ted on the side return

only need be removed. Do not remove the opening
cover.
COMPRESSORS
Units are ship ped with compres sor mountings facto ry-adjusted
and ready for operation.
CAUTION: Do Not loosen compressor mounting bol ts.
FILTERS
2" filters are supplied wi th each unit. Filters must a lways be
installed ahead of the indoor coil and must be kept clean or
replaced wi th sam e size and typ e. Dirty fi lters will re duce th e
capacity of the unit and will result in frosted coils or safety
shutdown. Minimum filter area and re quired siz es are s hown in
the Physical Data table.
SERVICE ACCESS
Access to all serviceable components is provided by the
follo w in g rem o vable panels:
Compressor compartment
•
Electri c Heat compartment
•
Side Supply & Return Air compartments (Two panels)
•
Blower compartment (Three panels)
•
Main control box
•

•
Outdoor Air compartment (Two panels)
•
Refer to Dimensions and Clearnaces Fig ure for locati on of
these access panels.
CAUTION: Make sure that all screws and panel latches are
replaced and properly positioned on the unit to
maintain an air-ti gh t se al .
THERMOSTAT
The room thermostat should be located on an inside wall
approximately 56" above the floor where it will not be subject
to drafts, sun exposure or heat from electrical fixtures or
appliances. Follow manufacturer’s instructions enclosed with
thermostat for general installation procedure. Color coded
insulated wires (#18 AWG) should be used to connect
thermostat to unit. Eight conducto rs are requ ire d.
The subbase on the low voltage thermostat includes an
"Emergency H eat" position on the system switch and a pilot
light. In the "Emergency Heat" position, the thermostat will
provide elect ric resist ance he at on ly. Th e com press ors wil l not
run. The pilot light wi ll indi cate th at the switc h is on "E M HT".

CONDENSATE DRAIN
Plumbing must conform to local codes. Use a sealing
compound on male pipe threads. Install a condensate drain line
from the 1" NPT f emale connectio n on the unit to an op en drain.
An alternate drain connection (1" NPT female coupling) is
provided inboard on the same centerline as the exterior
location.
NOTE: The condensate drain operates in a negative pressure

in the cabi net. The conden sate drain line MUST be
trapped to provide proper drainage.
Nine conductors are required for this application.
POWER AND CONTR OL WIRING
Field wiring to the unit must conform to provisions of the
National Electrical Code, ANSI / NFPA No. 70 (in U.S.A.),
current Canadian Electric Code (CEC) CSA C22.1 (in Canada)
and/or local ord inances. The unit must be electrically g rounded
in accordance with NEC and C EC (as spec if ied ab ove) and/or
local codes. Voltage tolerances which must be maintained at
the compressor terminals during starting and running
conditions are in di ca ted on the unit Rating Plate.

FIG. 5
- TYPICAL FIELD WIRING
The internal wiring harness furnished with this unit is an integral
part of a ETL and CGA design certified unit. Field alteratio n to
comply with electrical codes should not be required.
MUST BE USED so that water or moisture cannot
be drawn into the unit during normal operat ion. The
above waterproofing conditions will also apply
when installing a field-supplied disconnect switch.
A fused disconnect switch should be field provided for the unit.
The switch must be separate from all other circuits. Wire entry
at knockout openings require conduit fittings to comply with
CEC (in Canada), NEC (in U.S.A.) and/or local codes. Refer to
TABLE 2 -
the Dimensions and Clearances Figure for installation location.
If any of the wire supplied with the unit must be replaced,
replacement wire must be of the type shown on the wiring
diagram and the same minimum gauge as the replaced wire.
Electric al line must be sized proper ly to carr y the load . Each
unit must be wired with a separate branch circuit fed directly
from the meter panel and properly fused.
CAUTION: When connecting electrical power and control
wiring to the unit, waterproof type connectors
